In the context of graphing inequalities, what does a solid line indicate about the points on the line?

• Points are not part of the solution

• Points are part of the solution

• Points need further testing

• Irrelevant to the solution

What does a dotted line mean when graphing an inequality?

• The line's position is incorrect

• The line is optional in the solution

• Exclude the line from the solution

• Include the line in the solution

When graphing 'y < 2x - 1', where should you shade if using a test point (0,0) results in a false statement?

How do you determine which side of the graph to shade for the inequality 'y > -x + 3'?

• Shade above the line

• Shade below the line

• Shade on the line

• No shading is required

What is the purpose of using a test point in graphing inequalities?

• To find the slope of the line

• To draw the line more accurately

• To determine the correct side to shade

• To calculate the y-intercept

If the test point (0,0) makes the inequality false, where should you shade?

• No shading is required

• Opposite side of the test point

• Where the test point is

• Directly on the line

When graphing the absolute value inequality 'y < |x - 2| - 4', where should you shade?

• No shading is required

• Inside the V

• Outside the V

• Directly on the V

What indicates that you should use a solid line in graphing an absolute value inequality?

• The vertex is at the origin

• The inequality does not include 'equal to'

• The inequality includes 'equal to'

• The slope is negative
